Hypoxia’s Effects on the Shrimp Fishery in the Nor...

Our research is the first to investigate hypoxia’s effects on the harvest and economic dynamics of a Gulf of Mexico shrimp fishery. By linking hypoxia to impacts on fisheries, we ...

Impacts of Hypoxia on Fish and Fisheries in the No...

To protect fisheries and support ecosystem-based resource management in the northern Gulf of Mexico, we are developing modeling tools that will evaluate and simulate how large-scale changes in forcing factors ...

Integrated Ecosystem Modeling of the Causes of Hyp...

The largest low oxygen (hypoxic) zone affecting the United States is in the northern Gulf of Mexico, adjacent to the Mississippi River. This “dead zone” in the Gulf of Mexico ...

Mechanisms Controlling Hypoxia – Integrated Causal...

We’re examining the complex physical and biogeochemical relations that control and maintain the low-oxygen dead zone in the northern Gulf of Mexico (nGOM). We are combining field data from moored ...

Modeling Impacts of Hypoxia in the Northern Gulf o...

We are determining the effects of hypoxia (low dissolved oxygen) on reproduction of fish (Atlantic croaker) throughout the northern Gulf of Mexico to accurately model population outcomes and to assess ...

Operational Gulf of Mexico Hypoxia Monitoring

The Gulf of Mexico hypoxia monitoring cruise is an annual shelf-wide survey of the Gulf's hypoxic area (i.e., “dead zone”) and the survey is the metric used by the interagency ...

Synthesis and Integrated Modeling of Long-Term Dat...

We are integrating existing data sets collected in the Northern Gulf of Mexico to study hypoxia impacts on coastal ecosystems and associated fisheries. We are using probabilistic, data-centric modeling to ...

User-Driven Tools to Predict and Assess Effects of...

We are developing user-friendly, management-scale forecasting tools and quantitative indicators for hypoxia impacts on the Northern Gulf of Mexico ecosystem. We will assess minimum data needs to ensure these forecasts ...

Using Linked Models to Predict Impacts of Hypoxia ...

We are linking a suite of well-established models to quantify fish and shrimp population responses to combinations of nutrient loadings and planned river diversions. Our scenario analyses include different land-use ...

Bacterial Removal of Nitrogen, Methane from Gulf D...

NCCOS-supported researchers have determined the natural removal rates of nitrogen and the potent greenhouse gas methane from Louisiana's coastal waters. The study investigated patterns of pelagic denitrification (bacterial conversion of ...

Third Advisory Panel Workshop on Hypoxia Effects o...

The third Advisory Panel Workshop on Hypoxia Effects of Fish and Fisheries was held virtually on December 14, 2020 as part of an NCCOS NGOMEX project led by Dr. Kim ...

Smaller than Average Summer ‘Dead Zone’ Measured ...

NCCOS-supported scientists have determined that this year’s Gulf of Mexico “dead zone”—an area of low oxygen that can kill fish and marine life—is approximately 2,116 square miles, equivalent to 1.4 ...

Model Combines Reduced Nutrients, Increased Temps ...

A team of NCCOS sponsored scientists have enhanced a hypoxia model with an unprecedented, multi-decadal oceanographic dataset to predict the combined effects of reduced nutrient loading, increased temperature, and freshwater ...
